Windows 10: Re-instating Win 11 after it was wiped and replaced with Win 10 by a repair shop.

A virus required my laptop Dell Inspiron 3780 to be wiped, and the repair shop replaced the Win 11 OS with which it came when purchased with Win 10. How can I get the original OS back, without having to pay for it? Questions to Support have not been answered.

I am beyond happy with this OS, and wish to install Win 7 wiping Win 10, can someone offer me a step by step guide please

Wipe and install Win 7

Confusing.
I assume you mean "not happy" instead of "beyond happy".

At the very least you'll need:

1. A legitimate W7 install disk and Product Key
2. KB976932 Service Pack 1
3. Driver install files
4. KB3020369 Prerequisite for KB3125574
5. KB3125574 W7 SP1 Update Rollup (Windows will be updated to April 2016)

Then follow this tutorial:

Once you have successfully installed W7, the updates listed above and the drivers, install a program like Macrium Reflect and create at least 2 Backup System Images (on different external HDDs).

Once you have created the Backup System Images, you can risk downloading the remaining updates for W7.
I only install the Security-Only updates (and some fixes for them):



Note:
You'll also need to apply IE and .NET updates separately.
